Yeesh. This is written as if someone is just discovering rudimentary details of technology, manufacturing, and logistics. But instead of learning, they're repeating benign information in the most paranoid-judgmental way possible. "<i>Amazon ... would not explain why tracking is assigned only after a product has left a fulfillment center</i>". heh.<p>These batteries are made by Fujitsu? That seems quite upstanding compared to what I would guess. It sounds like there is/was a quality problem, but no actual details to put it in context. I don't know Fujitsu's precise reputation here, but it's possible Amazon could have switched to them <i>due to</i> quality issues somewhere else.<p>Shedding some light on supply chains is certainly a worthy goal, but this does not help.
